Why Energy storage lithium iron phosphate batteries inspires a great debate?

The advantages of energy storage lithium iron phosphate batteries:

1. The lithium iron phosphate battery has a long life, the cycle life is more than 2000 times, and the 3C cycle life reaches more than 800 times. Under the same conditions, lithium iron phosphate batteries can be used for 7 to 8 years.
2. Safe to use. The lithium iron phosphate battery has undergone strict safety tests and will not explode even in severe collisions.
3. Fast charging. Using a dedicated charger, the battery can be fully charged for 40 minutes at 1.5C, and the starting current can reach 2C.
4. The lithium iron phosphate battery is resistant to high temperature. The peak heat of the lithium iron phosphate battery can reach 350 to 500 degrees Celsius, and the working temperature range is wide (-20~+75℃) and high temperature (60℃).
5. The lithium iron phosphate battery has a large capacity, and its energy density is 3 to 4 times that of a lead-acid battery, 2.5 times that of a nickel-cadmium battery, and 1.8 times that of a nickel-metal hydride battery.
6. Disadvantages of energy storage lithium iron phosphate batteries:
7. Poor consistency. The service life of the iron phosphate battery pack is significantly lower than that of the monomer. Compared with other batteries, the life of lithium iron phosphate battery pack has no obvious advantage. In the second-hand market, there are a large number of battery packs that are retired before their expected life.
8. The low temperature performance is not good. When the temperature is lower than 0 degrees, the capacity drops rapidly, and the cycle performance is extremely poor at low temperatures.
9. During the sintering process during the preparation of lithium iron phosphate, iron oxide may be reduced to elemental iron in a high-temperature reducing atmosphere. Elemental iron can cause a micro-short circuit in the battery and is the most taboo substance in the battery.
10. Lithium iron phosphate battery energy storage technology will be an important potential market
